Differential Diagnosis for Green Vaginal Discharge in a 3-Year-Old
Single Most Likely Diagnosis
- Vaginal Foreign Body: This is the most common cause of green or foul-smelling vaginal discharge in young children. The presence of a foreign object, such as a small toy or piece of cloth, can cause an infection leading to the characteristic discharge.
Other Likely Diagnoses
- Bacterial Vaginosis: Although more common in adults, bacterial vaginosis can occur in children and is characterized by an imbalance of the normal vaginal flora, leading to symptoms like green discharge.
- Vaginal Yeast Infection: Candidiasis can cause a greenish or whitish discharge in children, though it's less common than in adults.
- Urinary Tract Infection (UTI): UTIs can sometimes present with vaginal discharge, especially if the infection has spread to the genital area.
Do Not Miss Diagnoses
- Sexual Abuse: It's crucial to consider the possibility of sexual abuse in cases of unexplained vaginal discharge or infection in children. This diagnosis requires a thorough investigation and examination.
- Gonococcal or Chlamydial Infection: These sexually transmitted infections (STIs) can cause green discharge and are critical to identify due to their implications for the child's health and potential abuse.
Rare Diagnoses
- Vaginal Tumor or Cyst: Rarely, a green discharge could be a sign of a vaginal tumor or cyst, which would require immediate medical attention.
- Congenital Anomalies: Certain congenital anomalies of the genital tract can lead to abnormal discharge, though these are rare and often identified at birth or during early infancy.
